Alternative PFAS-free back sheets for solar panels Innovative material solutions for solar panel manufacturers. With a long heritage in polymer science and co-extrusion, we support the solar industry with a growing family of high-performance co-extruded backsheets (where we are now the global market leader); along with conductive backsheets, specialty films, strips and sheets for a wide range of solar modules. Our backsheets are fully recyclable and fluorine-free. They not only lower your carbon footprint, but also reduce your module’s end-of-life cost, thus helping you contribute to a more circular solar industry.
